Creating LVMs During Installation

Creating logical volumes involves several steps. First, you create physical LVM partitions, then the volume groups you place these partitions in, and then from the volume groups you create the logical volumes, for which you then specify mountpoints and file system types. You can create LVM partitions during the installation process. Click New and select "physical volume (LVM)" for the File System Type. Create an LVM physical partition for each partition you want on your hard disks. Once you have created LVM physical partitions, you click the LVM button to create your logical volumes. You first need to assign the LVM physical partitions to volume groups. Volume groups are essentially logical hard drives. You could, if you wish, assign LVM physical partitions from different hard disks to the same volume group, letting the volume group span different hard drives. This approach is useful if you are combining several hard disks into one logical group. Once the volume groups are created, you are ready to create your logical volumes. You can create several logical volumes within each group. The logical volumes function like partitions. You will have to specify a file system type and mountpoint for each logical volume you create. The file system type for Fedora is normally ext3.
